IMPROVEMENT IN RFRIAGE'RATO'RS ANfD' FILTERS.

Specification forming `part of Letters Patent No. 188,650, dated March 20, 1877; application tiled* I Februariy 3, 1877.

To all 'whom it may concern:

Be it known that I, ANDREW MGCLAIN, of the city of Nashville, in the county of Davidson and State of Tennessee, have invented a new and valuable Improvement in Refrigerators and Filters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the-drawings is a representation of central vertical section of my refrigerator and lter, and Fig. 2 is a plan view of the same with the tops removed. Figs. 3, 4, 5, and 6 are detail views thereof.

This invention relates to combined refrigerators and filters; and it consists in the peculiar construction, combination, and arrangement of the parts hereinafter described.

In the accompanying drawings, A designates a tank or water-receptacle, which supports a refrigerator, B, and a filtering apparatus, C, annexed to said refrigerator, and hereinafter more particularly described. Said refrigerator B is provided with an ordinary hinged cover, B', immediately under which is a water-receptacle, C. At one corner of said water-receptacle is a sponge-box, D, having an inclined perforated hinged outer face, D1, and a perforated fixed verticaldouter wall, D2. The space between said outer wall D2 and the inside of the outer casing of the refrigerator forms a guideway, e, for a slide, E, which regulates the outiiow of water from said water-receptacle.

The perforations d in said vertical wall D2 are arranged above one another, so that the descent of the said slide may close all or only some of them, as preferred. The sponge d within said box D compels the water to ow slowly.` It also checks the outflow of foreign matter, and acts as, a coarse lter.

LAt the bottom of guideway e is a perforation, e', through which the water passes to the main compartment F of the refrigerator.

G designates the refrigerating chamber,

which juts into the middle of said compartment F, and is provided with a door, g, opening at the front of said refrigerator, the front wall of which refrigerator supports said chamber Gr.

The water from said perforation c' passes first into a space, H, partitioned off from main compartment F, at one corner thereof, and communicating therewith at the bottom. At the corner diagonally opposite to said space is a vertical passage, I, rising from the door of said compartment F to a point a little below the level of the top of same space H, and a little above the line of top refrigerating-chamber G. The water is thus compelled to circulate about the refrgerating-chamber Gr, and thoroughly cool the same, before passing out of compartment F, the ice being deposited in the corners of the compartment F which are most distant from door g.

From said passage I the water ows through an orice, z', into the bottom of inner filteringchamber J and rises through a perforated false bottom, j, in said chamber, and through filtering material which is placed thereon, to a perforation or perforations, j j. (Shown in Fig. 4.) Through said perforation or perforations the water flows into an end space, K1, partitioned off from a second filtering-chamber, K, but communicating therewith through upper perforations k1 and lower perforations k. The water ordinarily passes through said lower perforation, then up through a perforated false bottom, K2, of said chamber K, and the filtering material laid thereon, and finally out through perforation k2, near the top ofthe opposite partition, into a second end space, K3. The perforations k2 are a little below the line of perforations k. In case, however, the water Hows too freely into space K1, upper perforations k1 allow the excess to iiow into chamber K, above false bottom K2, and thereby prevent overow.

From second end space K3 the water, now thoroughly filtered, passes through bottom perforations 11.3 k3 into tank A, whence. it is drawn through tube A'. N, N1, and N2 are perforations near to and above the bottom of Y purpose set forth.

2. Refrigerating-chamber G, in combination with compartment F, having space H and tube I, arranged at diagonally-opposite cortners, substantially as and for the purpose set orth.

3. The combination of filtering-chambers J and K, end spaces K1 and K2, and perforations connecting said chambers and spaces, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ANDREW MGGLAIN.
